These were coiled in the parenchyma of the liver, and the lung and several were in fibrous capsulesattached to the mesentery. Closer examination on the dissecting microscope revealed 20 pronounced annulations on each of the organisms and an oral orifice was located on the ventral surface close to the anterior tip, flanked laterally by a pair of recurved hooks. These organisms were identified as “ymphs of Armillifer armillatus. 361 - Retour au menu DISCUSSION Intermediate hosts for A. armillatus as is the case with this chimpanzee get the infection either by consuming an infected snake, or food and water wbich bave been contaminated 6th the snake’s faxes (2). It is most probable that the chimpanzee brought the infection from its original wild habitat since none of the other 3 chimpanzees living in the same cage with the deceased one showed any sign of infection. The public health importance of this pentastome cari be significant especially in localities where apes are eaten by humans. This finding in a zoo chimpanzee adds yet another host on record in the West of Africa. Although A. armillatus has not yet been reported in chimpanzee, its occurrence in this host is not unexpected considering its wide host range. SUMMARY Nymphal staga of Armill~~er armillatus were found encapsulated in the organs of a captive chnnpanree from the Kane St& Zoo. The Chimpanzee is recorded as a new host in this region.
